The Bellari VP130 is a hybrid tube phono pre-amplifier and headphone amplifier with upgrades. This is class B rated at Stereophile, no easy feat for something not costing in the thousands of dollars. It is designed to enhance the sound quality of vinyl records and provide a warm, rich sound. The tube amplifier technology adds a vintage touch to the audio output. The upgrades include a much-improved power supply virtually eliminating the risk of hum. The feet were upgraded with solid aluminum feet with rubber inserts for better insulation. The casing is now damped internally to eliminate vibrations. Lastly the tube is now a Genalex Gold Lion, one of the best current production 12AX7 tubes. I have recently upgraded to a much more expensive tube phono preamp and thus with a heavy heart make this available to the next enthusiast. This product is suitable for home audio systems and can be used with a variety of turntables. Here is what is included: - Bellari VP130 with internal damping- Upgraded aluminum feet- Upgraded 12 AX7 tube: Genalex Gold Lion- Upgraded Power Supply: Enercell with specific tip to fit Bellari VP 130- Original Box- Original Manual All will be securely packaged and shipped to the 48 contiguous states only. Thank you for looking.
